My computer in A

Something interesting I've just noticed on my computer. My computer's fan is so loud that it produces an audible A. I somehow didn?t notice this before until just now when I was listening to Mahler 1 and 5. Coincidentally, both pieces have movements whereby the principal horn comes in with a long A. It was more obvious on the Hebert von Karajan and Berlin Philharmonic recording in which the orchestra was quite sharp (German orchestras are not tuned to A=442 unlike local bands and orchestras, in fact I heard somewhere that this German orchestra that tunes to A=447) and my fan was flat!

Speaking of sounds, every bang and creak you hear everyday has a pitch. I have this friend who for a period of time liked to tune every sound he heard (he has prefect pitch). Bang the door, G#. Tap a spoon onto a glass cup, B natural and so on. Even percussion instruments have pitch to them, like a bass drum pitched in G etc.

I?m simply just too bored. Hmmm, I shall explore my house for other sound emitting devices. Hehe!
